Intro

Go language is a programming language initially developed at Google in the year 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a statically-typed language having syntax similar to that of C.

Go is a general-purpose language designed with systems programming in mind.

Programs are constructed using packages, for efficient management of dependencies. Go programming implementations use a traditional compile and link model to generate executable binaries.

Go is fast! Go is extremely fast. The performance is similar to that of Java or C++. For our use case, Go is typically 40 times faster than Python.

Features​

  • Concurrent Language
    • Execute concurrently
    • Communicate between executing things concurrently
    • Goroutines are much cheaper than threads
  • Garbage collected
  • Strong and statically typed
  • Fast compile time
  • Compile to standalone binaries
  • Builds fast at scale
  • Goroutines
  • Channels
    • Channel are typed values that allow goroutines to synchronize and exchange information.
  • Select - The select statement is like a switch, but the decision is based on ability to communicate rather than equal values
  • Support for Interfaces and Type embedding
  • Production of statically linked native binaries without external dependencies

Features excluded intentionally​

  • Support for type inheritance
  • Support for method or operator overloading
  • Support for circular dependencies among packages
  • Support for pointer arithmetic
  • Support for assertions
  • Support for generic programming

Installing​

brew install go
